...I also believe that if a mine is officially abandoned the landowner cannot be sued if anything nasty happens underground...
Also of interest is that under section 151 of the Mines and Quarries Act 1954 there is a requirement for the owner (of the mineral rights in the first instance, but if they can not be found then the owner of the land) to secure
and maintain the surface entrance to every shaft or outlet with a sufficient enclosure or other device to prevent any person from accidentally entering the outlet or falling down the shaft. This statutory duty is irrespective of whether or not the mine is accessible from a public place.
Of course this does not necessarily mean the entrances must be grilled, the requirement can be met with just a wire fence around the opening. The question is if someone distorting a stock fence by climbing over it constitutes 'criminal damage' - one for the courts methinks! (although I suspect there'd be howls of laughter before a case got anywhere near a court). Certainly if the entrances have been 'secured' well, then any attempt to gain unauthorised access
would involve 'criminal damage'.

This was tested fairly recently at Wheal Jane where there was a toxic discharge from the adit. The water authority attempted to sue the mine owners but, as the mine was officially declared abandoned, the cost of the cleanup (approx £2million) came out of the public purse.
Was that incident in 1994? The law changed in around 1998/99 such that mine owners can be responsible for toxic discharges even though their mine is officially abandoned. This is one of the reasons why a number of small mines closed around that time - just prior to the introduction of the new legislation!
Talking to a friend who is minerals agent for a local council, apparently the landowner would be responsible for toxic discharges from the 'underground' section of their property. This means that if a mine entrance was discharging excessive toxic pollution then it would not necessarily be the responsibility of the landowner on whose property the entrance lies. It could be the responsibility of an adjoining landowner if the source of the toxic pollutants lay under his land. The problem arises from the fact that generally it's next to impossible to prove the pollution originates from one specific source - it's easier to work alongside, or take legal action against, the landowner on whose land the entrance lies!
